Publication number: 20240155156Abstract: Sampled data is packaged in checkerboard format for encoding and decoding. The sampled data may be quincunx sampled multi-image video data (e.g., 3D video or a multi-program stream), and the data may also be divided into sub-images of each image which are then multiplexed, or interleaved, in frames of a video stream to be encoded and then decoded using a standardized video encoder. A system for viewing may utilize a standard video decoder and a formatting device that de-interleaves the decoded sub-images of each frame reformats the images for a display device. A 3D video may be encoded using a most advantageous interleaving format such that a preferred quality and compression ratio is reached. In one embodiment, the invention includes a display device that accepts data in multiple formats.Type: ApplicationFiled: January 16, 2024Publication date: May 9, 2024Applicant: Dolby Laboratories Licensing CorporationInventors: Alexandros Tourapis, Walter J.

Patent number: 11979589Abstract: Methods and systems for frame rate scalability are described. Support is provided for input and output video sequences with variable frame rate and variable shutter angle across scenes, or for input video sequences with fixed input frame rate and input shutter angle, but allowing a decoder to generate a video output at a different output frame rate and shutter angle than the corresponding input values. Techniques allowing a decoder to decode more computationally-efficiently a specific backward compatible target frame rate and shutter angle among those allowed are also presented.Type: GrantFiled: November 13, 2023Date of Patent: May 7, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Robin Atkins, Peng Yin, Taoran Lu, Fangjun Pu, Sean Thomas McCarthy, Walter J.

Such data include at least the minimum, maximum, and average luminance values in the source data plus optional data that may include the color volume x and y chromaticity coordinates for the input color primaries (e.g., red, green, and blue) of the source data, and the color x and y chromaticity coordinates for the color primaries corresponding to the minimum, average, and maximum luminance values in the source data. Messaging data signaling an active region in each picture may also be included.Type: ApplicationFiled: October 13, 2023Publication date: February 15, 2024Applicant: Dolby Laboratories Licensing CorporationInventors: Tao CHEN, Peng YIN, Taoran LU, Walter J.

Publication number: 20240007678Abstract: In a method to improve the coding efficiency of high-dynamic range (HDR) images, a decoder parses sequence processing set (SPS) data from an input coded bitstream to detect that an HDR extension syntax structure is present in the parsed SPS data. It extracts from the HDR extension syntax structure post-processing information that includes one or more of a color space enabled flag, a color enhancement enabled flag, an adaptive_reshaping_enabled_flag, a dynamic range conversion flag, a color correction enabled flag, or an SDR_viewable_flag. It decodes the input bitstream to generate a preliminary output decoded signal, and generates a second output signal based on the preliminary output signal and the post-processing information.Type: ApplicationFiled: September 19, 2023Publication date: January 4, 2024Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Peng YIN, Taoran LU, Fangjun PU, Tao CHEN, Walter J.

Patent number: 11729400Abstract: Sample data and metadata related to spatial regions in images may be received from a coded video signal. It is determined whether specific spatial regions in the images correspond to a specific region of luminance levels. In response to determining the specific spatial regions correspond to the specific region of luminance levels, signal processing and video compression operations are performed on sets of samples in the specific spatial regions. The signal processing and video compression operations are at least partially dependent on the specific region of luminance levels.Type: GrantFiled: May 28, 2021Date of Patent: August 15, 2023Assignee: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Peng Yin, Guan-Ming Su, Taoran Lu, Tao Chen, Walter J.
